Over the years, [a craftsman's] hands take on a wisdom of their own. The potter knows by touch when something is out of round. The furniture maker knows by feel when something is straight. We who follow Tao therefore value what the hand does. We want a personal relationship with what we do and how we live: there is no better measure of this than the breadth of one's hand.
— Deng Ming-Dao, Everyday Tao
